Here’s a fun thing (not). I noticed today that the DSL connection was pretty rough, constantly reconnecting. It turns out after a lot of: run downstairs, check wires, DSL is OK, run back upstairs, still OK, start the treadmill and work, hmm it’s disconnected again, that this cheap treadmill is a big source of RFI that interferes with DSL.
(By the way, anyone considering getting the Roger Black GM-41001 Silver Medal Treadmill … DON’T! It may be very cheap, but it really is a piece of crap).
Why didn’t I get interference yesterday? Good question, but the router has been moved slightly, and perhaps the wire doesn’t pick it up so much.
Sadly, wrapping tinfoil around the phone line and earthing it did not work.
I ordered one of these mains conditioners with a big choke for £25 (about 10% of the cost of the treadmill). We shall see tomorrow if this works …
